Since the first scale 12 is moved toward the second scale 14, whether only one of the scales 12 and 14 moves or both of the scales 12 and 14 move, the position of the contrast portion 24 also moves, as shown in FIG. 2B The relative movement of the β scale shown is extremely small, smaller than the pitch lengths P1, ρ2 of the scales 12, 14 ^ However, the large movement of the contrast portion 24 is surprisingly clearly seen by the small movement of the scale 12 '14. The large movement of the contrast part 24 is determined by the choice of different pitch lengths of the two scales 12,14. Since the phase shift of the shot is equal to the length of one pitch, the contrast portion 24 is close to the end of the scale, as shown in the diagram in FIG. 2C, and the contrast portion moves at the full distance of the scale.
